World Class Service




Marlon came back for a second visit and he was beyond professional and explained our plumbing situation clearly and provided us with options. He did not try to overcharge us or charge us for services that were not needed.

Great service; informative and complete




Michael made sure to explain the workings of my furnace and made sure I understood what occurred to prevent the furnace from starting. Friendly, knowledgeable about his job as well the company he works for

Very professional and helpful




Michael was right on time, asked questions, listened to my answers, and talked me through his checking of my furnace idiosyncrasies. He even taught me things I didn't know about furnace filters!! It is running now, but he assured me that if anything went weird again, to be sure to call again.

Great as always




Jose has been my plumber of choice for years now and will continue to be. Great service, reasonable prices, and someone I trust, and there are not many. Jesus came with him this time and he is another example of why I will continue to do business with black diamond.

He arrived early! The office called and asked if he could come early. He was polite. He always made sure I knew where he was and what he was doing. It was a good experience.


Excellent service




Every time we need Black Diamond the service and people are extremely knowledgeable and courteous


Five star again




Once again the service I get from Black Diamond is efficient, friendly, knowledgeable. Thanks Andy and Jimmy.


Great service!




Clay was quick to analyze the problem and quick to fix it. Much appreciated since our system failed in the midst of the great September heat wave! And on the weekend besides! Thanks for doing a great job at a fair price.


knowledgable expert crews




Homeowners need expert quality techs and service, and the people at Black Diamond deliver big time! There isn't a problem they can't solve. I know this, becuse I've had them handle my home-projects over 10 years.


Excellent Service and Staff, as always




Juan helped make a "disasterous situation" much more bareable while remaining professional and courteous. Evaluated all possible causes and resolutions and kept me informed.
